Potential global distributions of an important aphid pest, Rhopalosiphum padi: insights from ensemble models with multiple variables.

Species distribution modeling is extensively used for predicting potential distributions of invasive species. However, an ensemble modeling approach has been less frequently used particularly pest species. The bird cherry-oat aphid Rhopalosiphum padi L.

Soil Physical Properties Affect Herbivory of in a Cork Oak Forest.

Studies have reported the important role of soil properties in regulating insect herbivory under controlled conditions or at relatively large scales. However, whether fine-scale variation of soil properties affects insect herbivory under natural conditions in forests is still unclear. We selected a 300 ha forest area where the leaf damage was mainly caused by (Lepidoptera: Notodontidae) and set 200 10 × 10 m plots within the area.

Examining CO and NO pollution and reduction from forestry application of pure and mixture forest.

Greenhouse gases (GHGs) carbon dioxide (CO) and nitrous oxide (NO), contribute significantly to global warming, and they have increased substantially over the years. Reforestation is considered as an important forestry application for carbon sequestration and GHGs emission reduction, however, it remains unknown whether reforestation may instead produce too much CO and NO contibuting to GHGs pollution. This study was performed to characterize and examine the CO and NO emissions and their controlling factors in different species and types of pure and mixture forest used for reforestation.

mRNA expression and DNA methylation in three key genes involved in caste differentiation in female honeybees (Apis mellifera).

In honeybee (Apis mellifera) colonies, queens and workers are alternative forms of the adult female honeybee that develop from genetically identical zygotes but that depend on differential nourishment. Queens and workers display distinct morphologies, anatomies and behavior, better known as caste differentiation. Despite some basic insights, the exact mechanism responsible for this phenomenon, especially at the molecular level, remains unclear although some progress has been achieved.
